About the Arduino PCB

Arduino is an open source ESP32 PCB design by GarethCooke, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 49.2 × 73.5 mm, with 63 components from 43 distinct parts.

Its main chip is the ESP32-S3-WROOM-1, from the ESP32 family. Other key parts include the MSGEQ7, LM2596S-5, AMS1117-3.3 and MAX9814. By type, the board carries 19 capacitors, 15 resistors, 7 connectors, 6 diodes, 5 ICs and 3 transistors.

It belongs with the iot & wireless designs in this gallery.

Arduino: common questions

What microcontroller does the Arduino use?

The Arduino is built around the ESP32-S3-WROOM-1, from the ESP32 family.

How big is the Arduino PCB?

The Arduino measures 49.2 × 73.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Arduino?

63 components, from 43 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Arduino design files?

From the GarethCooke/Arduino repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Arduino design in my own project?

Yes, under the terms of its GPL-3.0 license, which GarethCooke chose for the repository.

Can I test firmware for the Arduino without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
